UNITED STATES PATENT OFFICE ROTARY ENGINE.

Specification of Letters Patent.

Patented July 3, 1906.

Application filed April 19,1906. Serial No. 312,680.

To all whom it may concern:

Be it known that I, ERNEST H. TAYLOR, a citizen of the United States of America, residing at Ellwood City, in the county of Law-' rence and State of Pennsylvania, have invented certain new and useful Improvements in Rotary Engines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in rotary engines; and the invention has for its primary object to provide a simple and inexpensive engine from which a great amount of efliciency may be obtained from a minimum expenditure of steam or air.

Another object of this invention is to provide a rotary engine wherein positive and reliable means are employed for using the entire propelling forces of steam or air to revolve the sh aft.

A further object of this invention is to provide a rotary engine which will be strong and durable, positive in its action, highly efficient for the purposes for which it can be used, and free fromall danger of being injured by constant use.

With the above and other objects in view, which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination, and arrangement of parts to be hereinafter more fully described and claimed, and, referring to the drawings accompanying this application, like numerals of reference designate corresponding parts throughout the several views, in which Figure 1 is a vertical sectional view of my improved engine. Fig. 2 is a longitudinal sectional view of the same, partly in side elevation and Fig. 3 is a detail perspective view of a portion of the bearing-ring used in connection with the engine. Fig. 4 is a perspective view of one of the blades and its supportingarm.

To put my invention into practice I construct my improved engine of a suitable baseplate 1, carrying a vertically-disposed head 2. The head 2 is provided with a central inwardly-extending stub-shaft 3, carrying an eccentrically-mounted block or cam 4.

Secured to the head 2 by bolts and nuts 5 is a cylindrical engine-body 6, said body having its ends provided with annular grooves 7 7 to accommodate bearing-rings 8 8. The engine-body 6 is provided with two diametrically-opposed openings 9 9, and in said openings are mounted springs 10, which are adapted to bear against the rings 8 8 and force said rings outwardly. The rings upon their outer upper faces are provided with auxiliary bearing-rings 11 11, the object of which will be presently described.

Prior to mounting the cylindrical body upon the head 2 the head is recessed, as at 12, to accommodate a revoluble plate 14, said plate being journaled upon the stubshaft 3. Secured to the plate 14 by longitudinally-disposed tie-rods or bolts and nuts 15 is a cylinder 16. The cylinder is provided with a lurality of radial longitudinally-disposed s ots 17 17, and in each slot is mounted a blade 18. Each blade is provided with a rearWardly-extending arm 19, said arms passing through stufling-boxes 20 20, mount ed in the cylinder 16. The arms 19 extend inwardly toward the longitudinal axis of the cylinder 16 and are provided with spring held rollers 21, adapted to engage the block or cam 4 of the stub-shaft 3.

The base-plate 1 of the engine is provided with two bearings 22 22, in which is journaled a shaft 23, said shaft carrying upon its one end a pulley 24, while upon its opposite end is keyed a head 25, said head being adapted to engage the cylinder-body 6 and the cylinder 16, to which it is secured through the medium of the tie-rods or nuts and bolts 15.

The cylinder-body 6 is provided with two diametrically-opposed enlargements 26 26, having angularly disposed ports 27 27 formed therein. Secured in the enlargements 26 26 are the ends of pipes 28 28, said pipes communicating with the ports 27 27 and serving functionally as inlet and exhaust steam or air pipes for operating my improved engine. The pipes are controlled by valves 29 29 of a conventional form.

By the novel arrangement of the various parts of my improved rotary engine it will be observed that the bearing-rings 8 engage the plate 14 and the head 25, thus preventing any leakage of steam or air between the cylinder-body 6, the plate 14, and the head 25. The rings 11 11 are adapted to prevent the leakage of steam or air around the bearingrings 8 8, said rings being'normally held in engagement with the plate 14 and the head 25 by the springs 10, mounted within the longitudinally-disposed openings 9 9 of the cylinder-body. The block or cam 4, which is eccentrically mounted relative to the cyl- ICC inder 16, is adapted to normally hold one of the blades 18 of the cylinder in engagement with the inner walls of the engine body 6, thus partitioning the compartment 30, formed between the cylinder 16 and the engine-body 6. Assuming that steam or air is admitted through the port 27 upon one side of the engine, the steam or air impinging the blade 18 will revolve the cylinder 16, together with the head shaft "23, and pulley 24, while the cylinder-body 6 and its appurtenant parts will beheld stationary by the head 2 of'the base-plate 1. The steam or air employed for revolving the cylinder 16 exhausts through port 27 upon the opposite side of the engine-body from whichit enters, and by manipulating the valves 29 29 and reversing the pipes 28 28 the engine can be made to operate in a reverse direction from that in which it is shown.

The engine in its entirety is constructed of strong and durable metal, and the frictional engaging faces of the various parts of the engine may be hardened to reduce the wear of said parts to a minimum, and thereby increase the lasting qualities of the engine.

Such changes as are permissible by the appended claims may be resorted to without departing from the spirit, and scope of the invention.

What I claim, and desire to secure by Letters Patent, is

1. An engine of the type described embodying a base-plate having a head, a stubshaft carried by said head, cams carried by said shaft, a cylinder-body secured to said head, a cylinder revolubly mounted in said body, a shaft-carrying head secured to said cylinder, an end plate secured to said cylinder, bearing-rings mounted in said engine body, and engaging said plate and said shaft-carrying head, radiallv-disposed blades mounted in said cylinder, and actuated by said cams, when said cylinder is revolved, substantially as described.

2. In a rotary engine, a base-plate having an integral cylinder-head, a cylinder-body fixed at its one edge to said cylinder-head, a stub-shaft carried by the cylinder-head, a drive-shaft, a cylinder-head fixed on said drive-shaft, a cylinder-plate journaled on the stub-shaft, a cylinder carried by said rotatable cylinder-head and cylinder-plate, a cam carried by said stub-shaft, radially-disposed and the rotatable cylinder-head, radiallydisposed blades carried by said cylinder, and movable radially therein, and a cam on the stub-shaft for actuating said blades, substanti ally as described.

In testimony whereof I afiX my signature in the presence of two witnesses.
